Soil source heat pump system with heat pipe heat exchanger well

Abstract

The invention relates to a soil source heat pump system with a heat pipe heat exchanging well, comprising a heat pump unit and a well-shaped artificial water body with heat pipes. The well-shaped artificial water body is also called a heat exchanging well, the surface of the heat exchanging well and the heat ends of the heat pipes are used as heat exchanging interfaces between the heat pump system and soil, the heat pump unit exchanges heat with well water in the heat exchanging well, works to output heat to the outside. For reducing continuous soil temperature fall or rise caused by heat exchange, heat-exchanging interfaces between the well water in the heat exchanging well and the outside, including interfaces between the well water in the heat exchanging well and a solar heat-collecting device or other water sources are arranged. The soil source heat pump system with the heat pipe heat exchanging well is characterized in that most parts of heat pipes in radial distribution extend into soil outside the well wall, and the cold ends of the heat pipes extend into the well water in the heat exchanging well. The invention has the advantages that the heat pipes in radial distribution has a well mouth in a small area and great effective heat-collecting capacity. The surface of the heat exchanging well and the heat ends of the heat pipes are utilized to exchange heat with soil so as to greatly reduce pumped well water or even avoid pumping well water under the condition of satisfying heat and hot water supply loads. The invention provides an embodiment shown in an attached drawing.

Description

technical field [0001] The invention relates to a soil source heat pump system with a heat pipe heat exchange well. Background technique [0002] The existing water source heat pump system extracts groundwater for primary use only, and the recharge rate of most water source heat pumps is less than 50%. In order to conserve water resources, groundwater abstraction should be minimized. Contents of the invention [0003] The purpose of the present invention is to provide a soil source heat pump system with a heat pipe heat exchange well. [0004] The technical solution adopted by the present invention to solve the technical problem is to use a heat pump unit and a well-shaped artificial water body with heat pipes to form a soil source heat pump system with heat pipe heat exchange wells. Well-shaped artificial water body is also called heat exchange well. Most of the radially arranged heat pipes extend into the soil outside the well wall, and the cold ends of the heat pipes...
